If you've deleted someone and want to know if they've deleted you as well, here are some possible ways to do it:
1.Check out the features of your social platforms: Many social platforms offer features such as "friends lists" or "watchlists". You can check to see if you still see the other person's account in these lists. If the other person's account is not on the list, it may mean that he or she has also deleted you.
2.Search for the other person's account: Try searching for the other person's account on the social platform. If you can find the other person's account, it means that he or she may not have deleted you. However, if you can't find it, it may mean that the other person has deleted their account or set your privacy settings.
3.*Confirm with mutual friends**: If you have mutual friends, ask them if they can still see or interact with each other. If mutual friends can't see each other's messages either, they may have deleted you.
4.*Try to send a message**: You can send a short message to the other person, but don't expect a reply. If the message is sent, the other party may not have deleted you. However, if you can't send a message, or if you see a message like "The other person isn't your friend," it's likely that they've deleted you.
It's important to note that these methods aren't 100% sure if the other party has deleted you, as different social platforms may have different rules and features. In addition, the other party may have only temporarily disabled their account or set their account privacy settings. The most accurate way to do this is to communicate directly with the other person or obtain information through other reliable means.
